(a) HD 30495 combined S-index time series, including data from MWO (•), SSS (◦), SMARTS (﹩\blacksquare ﹩), CPS (﹩\blacktriangle ﹩), and HARPS (﹩\blacktriangledown ﹩), along with seasonal means (•), with error bars representing the error of the mean. The red curve is a three-component sine wave model of the stellar cycles, while the horizontal red line is our reference point for global activity minimum. (b) Zoomed portion highlighting higher-cadence SMARTS data, with a ﹩P=1.58\;\mathrm{year}﹩ sine wave plotted for comparison (blue dashed curve). (c) APT differential photometry brightness measurements in the combined Strömgren b and y bands, in milli-magnitudes. Differences shown are HD 30495 nightly measurements (•) and seasonal means (•) with respect to the comparison stars, as well as the difference between the two comparison stars (﹩\square ﹩). (d) Seasonal mean differential brightness difference in the b and y bands, in milli-magnitudes, with colored regions indicating brighter b (blue) and y (green) emission. A horizontal dotted line indicates the grand mean in all panels. Magnitude scales are inverted such that brightness increases in the upward direction. The observations shown in this figure are available in the electronic version of this publication. See Tables 3 and 4 in the Appendix.
